Abstract
An improved opto-electronic device includes a metallic anti-reflection mirror. The metallic anti-reflection mirror has a first metal layer that is disposed on the substrate of the opto-electronic device, a dielectric layer that is disposed on the first metal layer, and second metal layer that is disposed on the dielectric layer. This layer structure, in combination with particular layer thicknesses and materials selection, creates a cavity that enhances the optical field in second metal layer such that any stray light that is generated by or received by the opto-electronic device is substantially absorbed.
